Meter Types
Prepaid meters are set up just like any other meter - i.e. the meter must reference a meter type and the meter's configuration must reference a meter configuration type.
To set up prepaid meter types you must do the following:
• Define the meter configuration types that will be used for recording prepaid usage. Mark each of these configuration types as Prepaid . Define one register with the appropriate UOM (e.g. kWh ). See Setting Up Meter Configuration Types for more information.
• Define the meter types that will be used for prepaid metering. For each meter type, associate one of the Prepaid meter configuration types that you defined. You can also mark each meter type as Prepaid Capable. See Setting Up Meter Types for more information.
Note: 
Base logic does not require the meter type to be marked as Prepaid Capable. The Prepaid indicator on the meter configuration type is used to identify prepaid meters.
